Pet's info: Cat | Domestic Shorthair | Male | neutered | 8 years old
I've had a cat for around 9 years that is perfectly fine around me, but is extremely anxious and aggressive (hissing, scratching, running away) with anyone that comes into my apartment. It's been getting progressively worse over the years, from bareable to a point that I don't want to invite anyone over. I've tried all of the anti-anxiety remedies I've seen online, including the diffusers, etc. But nothing seems to work. He's had medical checkups in the past but all fine. Not sure what to do.

Poor Tomas! It sounds like he gets very anxious and stressed about being taken to new places, which is a fairly common problem in cats - this can certainly cause aggressive behavior similar to what you describe. He would probably be happier staying at home when you are out of town, so you may want to consider having someone stop by your house to feed him daily during your trips rather than taking him to someone else's home to stay.
It's possible that prescription anti-anxiety medication may also help with his behavior, so I would definitely suggest talking to your veterinarian about this when you get a chance. Feliway pheromone diffusers or a natural calming supplement like Zylkene or Composure may also be helpful for him.
